Count yourself fortunate if you get to hear a concert here. The Golden Hall is regarded as one of the four acoustically best concert halls in the world. Some 600 concerts per season (Sept-June) are presented here. Only 10 to 12 of these are played by the Vienna Philharmonic; these are subscription concerts, so they're always sold out long in advance. Standing room is available at almost any performance, but you must line up hours before the show. The box office is open August 16 to September 3 Monday to Friday 9am to noon (Mon-Fri 9am-8pm and Sat 9am-1pm the rest of the year; closed from July-Aug 15).
